Chapter 6 Safety Functions
Configure Only When No Safety Signature Exists
This setting instructs the GuardLogix controller to automatically configure an
Armor PowerFlex drive only when the safety task does not have a safety task
signature, and the replacement Armor PowerFlex drive is in an out-of-box
condition, meaning that a safety network number does not exist in the Armor
PowerFlex drive.
If the safety task has a safety task signature, the GuardLogix controller
automatically configures the replacement CIP Safety I/O device only if the
following is true:
•
The device already has the correct safety network number.
•
The device electronic keying is correct.
•
The node or IP address is correct.
For detailed information, see the user manual for your GuardLogix controller.
Configure Always
When the Configure Always feature is enabled, the controller automatically
checks for and connects to a replacement Armor PowerFlex drive that meets
the following requirements:
•
The controller has configuration data for a compatible Armor PowerFlex
drive at that network address
•
The Armor PowerFlex drive is in out-of-box condition mode or has an
SNN that matches the configuration
ATTENTION:
Enable the Configure Always feature only if the entire
integrated safety control system is not being relied on to maintain
SIL 2/PLd or SIL 3/PLe behavior during the replacement and functional
testing of the product. If other parts of the integrated safety control
system are being relied upon to maintain SIL 2/PLd or SIL 3/PLe, make
sure that the controller’s Configure Always feature is disabled.
It is your responsibility to implement a process to make sure proper
safety functionality is maintained during device replacement in safety
control systems that are not being relied upon for SIL 2/PLd or
SIL 3/PLe. See the GuardLogix user manual appropriate for your Logix
5000 controller:
